A Sacroiliac Fusion (SI Fusion) is used to treat pain in the lower back, hips and buttocks as a result of a spinal condition known as Sacroiliitis. Sacroiliitis creates instability at the S1 vertebrae of the spine. The S1 vertebra is the lowest of the lumbar spinal vertebrae and is responsible for fusing the sacral spine to the pelvis. When this vertebrae becomes unstable, it can create radiating pain in the lower back, hips and buttocks.
How It Is Performed
An SI Fusion Surgery involves the surgeon making a small lateral incision at the sacral spine level. Once this incision is made, small triangular implants are used to fuse the sacroiliac joint. These triangular implants allow the joint to move and flex more naturally than a squared implant. This stabilization results in the relief of pain in the lower back as well as hips and buttocks.
The entire procedure is carried out utilizing a Minimally Invasive approach that minimizes tissue and muscle dissection.
